Do serum progesterone levels on the day prior to Day 5 Embryo transfer influence pregnancy outcome in artificial frozen-thaw embryo transfer cycle?

Background: Progesterone (PG) is an essential hormone in the process of implantation and pregnancy maintenance. Frozen-thawed embryo transfer (FET) being performed worldwide. This study was designed to investigate whether serum progesterone levels on day prior 5 frozen-thawed hormonally prepared endometrium correlates with outcomes. Materials Methods: A single center longitudinal observational conducted at infertility over a period three months from October 2022 December 2022. The participants were patients attending who satisfied inclusion exclusion criteria. total 30 included this study. Serum measured starting (P0) four (P4), transfer. Data analysis using SPSS version 21. Results: mean (SD) age those had positive outcome 34.22 (1.26) years negative outcomes 39.92 (2.11) difference significant (P = 0.001). 0 found be 0.61 (1.19) ng/ml 0.28 (0.27) but, not 0.347). 4 10.84 (8.13) 8.13 (3.81) 0.039). Conclusion: Pregnancy loss increases measurements could used assess technique treatment. Monitoring PG can done for diagnosing potential luteal support defects before performing FET artificial cycle (AC).
